Duplicate Advisory: Nuxt dev server vite-node IPC socket is world-connectable on Linux
Nuxt versions 4.0.0 before 4.4.7 and 3.18.0 before 3.21.7 have a vulnerability in the development server on Linux where the vite-node IPC server binds to an abstract-namespace Unix socket without permission restrictions. This allows local unprivileged users to connect to the socket and potentially read sensitive files such as .env and SSH keys through the SSR plugin pipeline. Production builds are not affected as this IPC server runs only in development mode.
AI Analysis
Technical Summary
Nuxt 4.0.0 before 4.4.7 and 3.18.0 before 3.21.7, when running the development server (nuxt dev) on Linux, binds the vite-node IPC server to an abstract-namespace Unix socket without permission restrictions. This misconfiguration allows local unprivileged users to enumerate and connect to the socket. Exploiting the unprotected module request handler, attackers can read arbitrary files including sensitive configuration files like .env and SSH keys through the SSR plugin pipeline. The vulnerability does not affect production builds since the IPC server is only active during development.
Potential Impact
Local unprivileged users on Linux systems running the vulnerable Nuxt development server can connect to the IPC socket and read arbitrary sensitive files, potentially exposing secrets such as environment variables and SSH keys. This compromises confidentiality but does not impact integrity or availability. Production environments are not affected.
Mitigation Recommendations
A patch is available for this vulnerability. Users should upgrade Nuxt to version 4.4.7 or later (for Nuxt 4) or 3.21.7 or later (for Nuxt 3) to remediate this issue. Since this affects only the development server on Linux, avoiding running the development server on multi-user systems or restricting local user access can reduce risk until patched.
